Every job starts with a real diagnosis, not a guess — here's the full scope of what our HVAC repair technicians handle across Wellesley, MA.
Compressor Diagnostics & Replacement
We test start capacitors and windings before recommending a full swap, since not every hard-start symptom means a new compressor. Techs handling compressor diagnostics & replacement carry the specific parts and tools this job calls for, not a generic kit.
Capacitor & Contactor Repair
We test capacitance against the rated microfarad value rather than replacing parts on a hunch. This is one of the most requested HVAC repair calls we get across Wellesley, MA.
Refrigerant Leak Detection
Electronic leak detectors and UV dye trace a slow leak back to the coil, line set, or schrader valve. This is one of the most requested HVAC repair calls we get across Wellesley, MA.
Blower Motor & Fan Repair
A blower that hums but doesn't spin, or one that's pulling excess amperage, gets tested under load, not just visually inspected. This is one of the most requested HVAC repair calls we get across Wellesley, MA.
Circuit Board & Control Diagnostics
A blown board is sometimes a symptom of a bigger electrical issue we'll flag. Techs handling circuit board & control diagnostics carry the specific parts and tools this job calls for, not a generic kit.
Thermostat & Wiring Troubleshooting
Short cycling, systems that won't call for heat or cool, or a blank thermostat screen often trace back to a wiring fault rather than the unit itself. This is one of the most requested HVAC repair calls we get across Wellesley, MA.
